Leviticus 13:52-54

Amplified Bible

⁵² So he shall burn the garment, whether the warp or woof, in wool or linen, or on anything made of leather in which the mark occurs; for it is a malignant leprosy; it shall be burned in the fire.

⁵³ “But if the priest sees that the mark has not spread in the garment, either in the warp or the woof, or on anything made of leather, ⁵⁴ then the priest shall order that they wash the thing in which the mark occurs, and he shall quarantine it for seven more days.
